Romweber joined Mitch Easter and bassist Faye Hunter to form Let's Active when the drummer was just 17. Romweber played on both the 1983 Afoot EP and Cypress, the 1984 debut full-length by Let's Active. However, she left the band shortly after.

Following her time in Let's Active, Romweber co-founded the group Snatches of Pink and performed with her brother as the Dex Romweber Duo. In 2014, she helped Easter stage a Let's Active reunion during a benefit show.
